most things i do, i just grind that dude off...if im doing something that will be under alot of load but the weld is required to be ground off.....from what iv'e read and understood, if the weld goes east and west, grind norht and south vice versa...because the grind marks can weaken it if done wrong........i haven't really had any bad experiences grinding. i had a cwi as an instructor and he explained that all to us. he was picky and, usually right.
